- Figure {77 is ,an elevat on of um lockingthe upper .end thereof being formed with ahorizontal substantially semi-circular ,Iseg- .Inent 1.0, while the-lower end thereof of j videned it'ormation and 7 provided with openings 11-11; This segm ent .10 is preferably formed integral with the plate 9, said plate and segment being preferably stamped-16m ,a' strip of sheet'metal, afterivhi'ch the-.Isgment is turned over atright angles as indicated more clearlyein ,Figure 4.,the stamped unit being clearly disclosed in Figure 8.

jTheends ofthe segment 10 arethenvturned downwardly ,to provide a a pair of attaching ears 1 2.'12 for apu'rposel erjeina'fter more fully described. Furthermore. this segment 10- is provided throughout, substantially [its entirelength with spaced circi larvopeni'ngs 13, the purpose of which will alSohehQllQinafter-fully set forth.

For arrangement upon the opposed side .of I a valve body is, another. clamping plate "14:, the upper end thereofibeing considerably ,wiclenecl soas'to provide ears 15\15 formed with openings .1 to register with, the openings inthe ears -1212 of thesegment .10, so that the 7 same may I be interconnected by screws 1616. Furthermore, the lowerendiof the plate lj l; is also widened and provided at the ends of this widenedportion vithl openings re gis tering With, the openings 1.11 11 "in the first mentioned clamping plate 9, se-that Qthese plates may befurther secured at: their lower ends byelongatedscreWs"17}17.

The-invention f urther consists of a; two plate clamp.- designated generally by the reference character 18. the same consisting of a pair of clamp plates ,19 and 20.1thatare vshaped for disposition overlthe; innereheaded end-of the valve stem handleBMas clearly disclosed-in Figures 1 and 3. @T he four. corners ofthese lates are spaced from th e handle and hea man secured together bv se't; screwsor the like. 21. The rear edges of theseplates 19 and 20 are rformed directly abovethe segment-1 0, wit 1 31 ,O ill' 'avvs 19' and 20, respectively. ftl atco mbine to form a sleeve thatis threaded internally fo recei in v hr le fpi gu d 2 the npper iend of which is cl'osed and proyided ,w th a knurled thumbnut 23. slidableiwiththis guide 22 is a short plungerl24r, arranged upon the lower end of a vertically ex nd n lp 125 tha i ena l emen .Zan breninefin th up cha 9 t ide, asclearlydisc 'osed in ,F' The of tlie plu ge -QA i valve handle plates 19' and 20 is'a thumb lever 29, the inner end of which is forked asat for engaging within notches 31-31 and the sides of the pins 25 as clearly disclosed in Figure 7. Threaded through an opening in the thumb lever 29 in back of its 'pivotal'connection to the plates 19 and 20 is a thumb screw 32, that when screwed downwardly will engage the upper edges of the plates 19 and 20, for preventing the pivotal action of the same in a direction to cause the raising of the plunger carrying pin 25 with the result that when the tit 26 of the plunger is arranged within one of the openings of the segment 10, the handle cannot be accidentally turned from a set position.

The particular operation, as well as the detailed features of construction will be readily apparent to those skilled in the art, and will furthermore appreciate that I have considerably improved upon the device shown and described in the previously mentioned application for patent.
